### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Sure, Git Annex is great as always. I use it several times a week with my multigigabyte
backups, where it gives structure to my image-based backup routines, so you could
say I'm a believer. :)
